Karnataka NEP referred 'Pythagoras Theorem' as fake news
Tags: Popular State News
A position paper on National Education Policy (NEP) 2020 by the Government of Karnataka has described Pythagoras' theorem as "fake news".
Important facts
The Pythagorean theorem has been disputed in many international forums. Pythagoras claimed this to be his theory.
The Karnataka NEP mentions a text called the Baudhayana Sulbasutra, in which the specific verse refers to the theorem.
About Pythagoras
Based on evidence, the existence of the Greek philosopher Pythagoras is believed to be around 570–490 BC.
However, it is believed that mysterious elements were present around him, because of the secretive nature of the school/society he founded in Italy.
Relatively little is known about his mathematical achievements, as no evidence exists of his own writing today.
What is Pythagoras Theorem?
The Pythagorean theorem describes the relationship between the three sides of a right triangle (one of which is 90°).
Its Equation is a² + b² = c²
where a and b are the two perpendicular sides, and c is the length of the diagonal side.
If any two sides of a right triangle are known, the theorem helps you calculate the third side.
Reasons why Vedic mathematicians knew this before Pythagoras?
There are several references in the Sulbasutra, which are written by Vedic Indians and refer to the rituals performed during yaganas.
The oldest of these is the Baudhayana Sulbasutra.
The period of Baudhayana Sulbasutra is not certain. It is inferred on the basis of linguistic and other secondary historical considerations.
In more recent literature, the Baudhayana Sulbasutra is taken from around 800 BCE.
There is a statement in the Baudhayana Sulbasutra called the Pythagorean theorem (this was known as a geometric fact, not a 'theorem').
Yagya rituals included the construction of altars (altars) and fire pits (fire) in various shapes such as isosceles triangles, symmetrical trapezia and rectangles.
The Sulabasutras describe the effort towards producing the prescribed shape of these figures.
How did the Knowledge of Equation Evolve?
The earliest evidence is from the Old Babylonian civilization (1900–1600 BC). They referred to this as the diagonal rule.
The earliest evidence comes from the later period of the Sulbasutras.
The oldest surviving axiomatic proof of the theorem is in Euclid's Elements from about 300 BC.
